Waterproofing of roof coating is a necessary measure that performs an important function: it preserves the roof from shattering impact of atmospheric moisture and other different aquatic solutions.
Waterproofing is better to be performed on the house construction stage, when taken measures will not only help you to increase the coating lifespan, but also to protect the building in whole. Besides, such additional building humidity protection measures during the construction will save your money in the future.
Roof waterproofing specifications
Roof waterproofing materials that are used for waterproofing of roof coating performance, should have certain qualities:
- water resistance;
- mechanical strength;
- heat resistance.
One unnecessary, but quite preferable specification — heat-saving function. The combination of humidity and cold protection in one material is an ideal solution for you house.
Waterproofing materials for any type of roof selection
Most often the roof is covered by bitum materials. This very coating is one of the most popular and commonly used coating for plane roof waterproofing on present-day construction market.
Some time ago three main materials were used for waterproofing of any roof type: rubberoid, asphalt felt and asbestos felt. Now they fade into insignificance, because polymer-bitum coatings replace it. These roll melting materials have in its base glass fibre cloth and polyester undisposed to rot.
The utilization of materials of new generation for roof waterproofing guarantees strength, reliability and long roof service lifetime. Waterproofing with roll materials and mastic are performed on roofs with slope ratio to 60 degrees. In general, the roof dip angle defines the number of waterproofing layers, including the number of reinforced mastic layers.
The waterproofing can be performed for different types of roof ыекгсегку. It can be wood, any metal, concrete. Besides, the roof covering can be applied to old covering or asbestos sheeting.
Roof waterproofing sometimes can be performed with mastic. In this case roll roof materials can’t be used. Thus, the mastic roof is created. Its advantage lies in jointless membrane that is obtained in the end. Besides, such covering is created directly on the roof, there is no need to perform any additional pre-construction activities. The mastic also has good adhesion to concrete, different metals, and bitum materials.
Bitum-polymer mastics are notable for a number of advantages:
– high strength;
– any aggressive environment, corrosion and ultraviolet emission resistance;
– wide utilization temperature limits from -60 to +100˚С.
